Description

When using an ItemTemplate of either FlexLayout or HorizontalStackLayout the Label item is not visible. When using a Grid, the items are visible but sizing padding is not applied.

Steps to Reproduce

1: create maui app
2: Add CollectionView to a page and set the IsGrouped to true and bind a grouped collection to the ItemsSource property
3: set simple ItemTemplate that uses FlexLayout, HorizontalStackLayout, or a Grid to display a Label bound to a Property on the item model setting Padding and Height properties on the controls
4: Run on Windows notice the template is respected
5: Run on Android, depending on what container is used for the Label either nothing is visible, or a minimal row will appear for the Label causing overlap next row item
